跨5G微运营商多租户实现网络切片通信业务分发

Achieving Network Slice Communication Service Distribution across 5G Micro-Operator Multi-tenants

摘要:

网络切片是一种将网络功能从一个尺寸适合所有人的逻辑隔离到一组不同切片的方法,其中每个切片负责特定的网络要求。同样,微运营商的概念也是针对垂直特定服务的5G本地部署。当跨接入网和核心网创建网络切片实例(NSI)时,重要的是要了解如何将来自创建的切片实例的通信服务分发给不同的租户及其最终用户。在这方面,我们提出了一种用于本地5G微运营商部署场景的网络切片通信服务分发技术。这通过将3GPP定义的通信服务管理功能(CSMF)扩展或利用到多租户管理器和通信服务编排器中来实现。我们进一步描述了通信服务编排器将如何解决在将网络切片实例分发给多个租户期间可能存在的所有可能的多租户切片情况。本文介绍的通用技术不仅为跨不同微运营商租户的网络切片通信服务分发提供了可研究的解决方案,而且为支持未来用例铺平了道路,特别是当分配的切片负责多个租户或租户请求多个NSI时

英文摘要:

Network slicing is the means of logically isolating network capabilities from a one size fits all to a set of different slices where each slice is responsible for specific network requirements. In the same light, the micro-operator concept is targeted at local deployment of 5G for vertical specific services. When a network slice instance (NSI) is created across the access and core networks, it is important to understand how the communication service from the created slice instance will be distributed to different tenants and their end-users. In this vein, we propose a network slice communication service distribution technique for local 5G micro-operator deployment scenarios. This is achieved by expanding or leveraging the communication service management function (CSMF) defined by 3GPP into a multi-tenant manager and a communication services orchestrator. We further describe how the communication service orchestrator will address all the possible multitenant-slice situations that can exist during the distribution of a network slice instance to multiple tenants. The generic technique introduced in this paper will proffer a researchable solution for not only network slice communication service distribution across different micro-operator tenants but pave the way to support future use cases especially when the allocated slice is responsible for multiple tenants or when a tenant requests multiple NSIs
